Quantum Tomography From Few Full-Rank Observables

چکیده
It was proven in [8] that the PhaseLift algorithm recovers signals x ∈ Cn exactly from m = O(n log n) measurements {|〈x, zi〉|2}i=1 with high probability when the measurement vectors zi ∈ C n are iid gaussian and that this procedure is provably stable with respect to measurement noise under the same assumptions. To be precise, this means that in the noiseless case, for a fixed x ∈ Cn and defining the linear operator A : X ∈ Cn×n 7→ {Tr(Xziz∗ i )}i=1, the program

Measuring Entanglement in a Photonic Embedding Quantum Simulator.
Measuring entanglement is a demanding task that usually requires full tomography of a quantum system, involving a number of observables that grows exponentially with the number of parties. Recently, it was suggested that adding a single ancillary qubit would allow for the efficient measurement of concurrence, and indeed any entanglement monotone associated with antilinear operations. Here, we r...
متن کاملQuantum Tomography of Semi-Algebraic Sets with Constrained Measurements
We analyse quantum state tomography in scenarios where measurements and states are both constrained. States are assumed to live in a semi-algebraic subset of state space and measurements are supposed to be rank-one POVMs, possibly with additional constraints. Specifically, we consider sets of von Neumann measurements and sets of local observables. We provide upper bounds on the minimal number o...
متن کاملQuantum tomography via compressed sensing: error bounds, sample complexity and efficient estimators
Intuitively, if a density operator has small rank, then it should be easier to estimate from experimental data, since in this case only a few eigenvectors need to be learned. We prove two complementary results that confirm this intuition. Firstly, we show that a low-rank density matrix can be estimated using fewer copies of the state, i.e. the sample complexity of tomography decreases with the ...
متن کاملObservable measure of bipartite quantum correlations.
We introduce a measure Q of bipartite quantum correlations for arbitrary two-qubit states, expressed as a state-independent function of the density matrix elements. The amount of quantum correlations can be quantified experimentally by measuring the expectation value of a small set of observables on up to four copies of the state, without the need for a full tomography. We extend the measure to...
متن کاملDynamics and thermalization in finite one-dimensional systems
We utilize quantum quenches to study the dynamics and thermalization of hardcore bosons in finite one-dimensional lattices. By means of full exact diagonalization, we show that far away from integrability few-body observables thermalize. We then study the breakdown of thermalization as one approaches integrable points [1, 2]. Insights on the different regimes are gained by means of eigenstate e...
